Complaint
| Basic Applications | Films | Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others |
| Sheeting | Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC | |
| Paper and PaperBoard | Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials | |
| Textiles and Nonwovens | Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products |
| Extended Applications | Inverted Cup Method | Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cups are required |
| Artificial Skin | Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test water vapor permeability of artificial skin | |
| Medical Products and Accessories | Including plasters, aseptic wound protecting films, face masks and scar sticks | |
| Solar Back-Sheets | Including solar back-sheets | |
| LCD Monitor Films | Including LCD monitor films | |
| Paint Films | Test water vapor permeability of various sorts of paint films | |
| Cosmetics | Test water vapor permeability of cosmetics | |
| Biodegradable Films | Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films |
